What defines trace minerals?

Trace minerals are defined as inorganic elements that play crucial roles in various bodily functions and are required in very small amounts compared to macrominerals. These minerals include iron, zinc, selenium, copper, manganese, and others, each contributing to processes such as enzyme function, hormone synthesis, and maintaining immune function. Their significance lies in the fact that, despite being needed only in trace amounts, they are essential for proper physiological functioning, highlighting the importance of a balanced diet that includes these minerals.

The other options do not accurately capture the definition of trace minerals. While some minerals are required in larger amounts, trace minerals are characterized by their minimal requirement. They do contribute to energy production, but they are not predominantly defined by this function. Finally, although some trace minerals can be found in plant sources, they are not exclusively or predominantly sourced from plants. Instead, a variety of foods including meats, grains, and seafood can provide these essential nutrients.
